(Closed) Inviting significant others to dancing only?

This topic seems to have been covered elsewhere, but our situation is just al ittle different, so please bear with me! We are having our ceremony and reception at the same place. When making our guest list, we realized that some of our cousins and friends (I have 12 of them) have boyfriends, but “no one special”. We realized that to give all of our friends/family who were seeing someone +1s would drastically increase our numbers, we made the rule that you have to live with the person for them to be invited.

So, now a couple people want to have their others come only for dancing. I’m starting to get nervous that this might get out of control. I’ve never met any of these others, so they are unknown to us and most of my family/friends. I don’t mind a couple people, but if at the wedding people find out that one person got to bring their other, then they might be upset that they didn’t get to bring theirs too. Am I worrying too much (as usual)?

Also, do we have to tell the venue that a couple extra people will be coming for the dancing? As of right now, there are only 2, but I don’t want to have the venue get upset on the day of. What’s the etiquette?

The invites were addressed to just hte cousins/friends (no “and guests”). I originally told my one cousin (who started the whole thing) that his date could come for dancing, but I didn’t think about the open bar. Hmmm…

I think it’s weird that these other people weren’t invited to the wedding and then all of sudden show up. In My Humble Opinion, it may change the dynamics of the party not to mention increase your bar bill. But, it’s not really a big deal.

I’d let the venue know, it’s a pretty common thing to do, maybe not for SO’s but these are more like new boyfriends right?

I know venues have a whole new set of rules when you tack on the “W” word, but for prom we had a certain number of teachers we were allowed to invite for the dancing portion with no meal to save money. People definitely do it.
